soap, it is essential that some means he employed which will allow of the replenishing of the liquid contents of the container and which will also prevent. the container contents from contamination.

It is evident, therefore, that-such means must be of a character as will allow of easy access to the interior of the container for purposes of filling and which can be replaced, for purposes of protecting the container contents.

In the generally employed soap containing and dispensing devices, it is usual to employ a metallic plug, stopper, or cap, capable of be ing inserted within, or caused to cover, the upper open portion, or neck, exit of the container when it is desired to protect the c011- tents, and capable of being withdrawn, or removed, when it is desired to introduce liquids into the container.

These devices, therefore, comprise at least two separable parts, the container and the closure means, and as the closure means are so constructed that their use requires the employment of a key, or similar device, at least, three separable members constitute the generally employed operating means.

These devices have the disadvantage that the loss of one of the separable elements,

such as the key, rendersthe device inoperative. I I

Another disadvantage of devices of the character described is that the presence of' metals is objectionable in manycases, either because the contents of the container attach the metals with which. they come in contact, or because the contents cause the several members of thedevice to adhere together, thus making it difiicult, and, at times, impossible, to separate them from each other without breakage.

Many acids and alkalis have the first men tioned effect, while other liquids, and especially liquid'soap, possess the property of causing the metallic, or the metallic and glass, or porcelain, members to strongly ad here to each other.

While I have referred particularly to liquid soap containers, my device is not limited I to that particular class ofcontainer, but can be employed equally advantageously with other containers, such as collapsible tubes.

My device overcomes all of the above,and other, objectionable features of the described closure means, as will be evident upon a consideration of my specification and accompanying drawings.

Among the advantages and properties of my device are the following 1t has no separable members, thus overcoming the possibility of the loss of parts with consequent inoperativeness, it requires no special key, or device, for opening, itis easily and rapidly opened and closed,thus saving considerable time in filling the container: the air-vent of the device may be made to indicatevthe place of opening; itis non-metallic, and hence, is not subject to the above-mentioned chemical and physical objectionable features; it is a permanent feature of the container and is removable only with. great difficulty, and hence, is not liable to malicious removal; it is positive in action economicalin construction and easy of operation. I I i The accompanying drawings with their description disclose the value and many advantages of the device of my invention.

In the accompanying drawings, illustrating modifiedforms of the device of my invention, similar parts are designated by similar numerals.

through the line 55 Figure 5 is a section of Figure 4; v

Figure 6 is a vertical section showing a modified form of my closure device employed with acollapsible tube.

The particular form of the device of my ii'ivention, shown in Figures 1, 2 and 3, comprises a rubber valve disk composed of the annular valve-member l0 and the annular flange 1.1, one portion 12 of the valve member 10 being integral with, or fixedly attached to, the flange 11, the flap, or free portion 13 of the valve member 10 being capable of abutment upon the flange 11. The

valve flap 13 has a hole, or vent, 14, so positioned that it is not closed by the abutment of the flap 13 upon the flange 11. p

A retaining member comprises the inter nally threaded collar 15 having the inwardly annular flange 16, the diameter of the collar 15 being such that the flange 11 of the valve member will fit snugly therein and the diameterof the opening inth-e flange 16 is such that it will abut slightly upon the inserted valve member but allow of the 1 forced passage of the valve flap 13 therethrough. V r In the drawings, the device is shown attached to a liquid soap dispenser comprising the soap receptacle 17 maintained in fixedupright position by the bracket 18, the liquid contents of the receptacle 17 being allowed to escape through the exit 19 by a pressure upon the valve 20. The neck 21 of the receptacle is externally threaded to mesh with the internal threads of the collar 15.

. In assembling the device, the valve disk is inserted within the retaining member and positioned so that the flange ,11 abuts firmly upon the inner face of the collar flange 16..

The collar is then screwed upon the neck 21 of the soap dispenser, cement 22 being employed, if desired, in order to make a jointurev that can be-broken only with chiliculty. The collar is screwed downwardly as far as conveniently possible, in order that the pressure of the retainer flange 16 upon the valve flange 11 will force the latter firmly 7 upon the upper face of the receptacle neck 21, thus forming a practicallytight jointure. When it is desired to fill the receptacle 17, the valve flap 13 is pulled outwardly and up- I wardly, by the insertion of a wire or other suitable device through the vent 1 1,01 other means can be employed for this purpose.

The valve flap 13 is then in the position mdicated by the dotted lines of Figure 1.

This allows of a comparatively large free opening 1D the valve diskthrough which the liquid may be introduced into the receptacle.

hen it is'desired to close the receptacle,

the valve flap l3 is forced downwardly beneath the retainer collar 16 and is thus held firmly in a closed position. i

It is to be noted that, when the de in closed position, the valve flap 13 abuts receptacle 17, and if positioned opposite the upon the upper face of the flange 11, thus preventing further downward movement.

The vent 14 serves for theadmission of air during the withdrawal of the contents of'the fixed, or hinged-like, portion 12 of the valve member, serves as an indicator as to which portion oi the valve disk is unattached to the flange 11, and, hence, is the valve flap portion,

. to be moved for purposes. of filling.

In themodilication of my device, shown in Figures 4' and 5, the vent 23, instead of being in the valve member 10, as shown vice is.

above, is in the valve flange 11 and is capable of alignment with a vent in the retainer collar 16. It is preferable to; have the flange vent 23 somewhat elongated, in order to be assured that it is in alignment with the vent 2 1. V

Figure 6 illustrates a modification of my device applied to a collapsible tube 25. In this form of my device, the air vent is omitted, as the valve serves to maintain the material within the tube, a pressure upon the latter forcing the contents against the inner face of the valve flap 13, opening it and allowing the escapeof the material, or the valve flap can be opened by other means, as by means of a fingernail, for instance, When it is desired to close the; tube, the valve flap is forced downwardly and, under the retainer collar 16, as described above.

7 It is obvious that departure may be made from the specific construction, as shown, for

instance, tie top faceof the valveinember 10 may be flush with, orbelow,the top face y of the retainer collar '16,'or flush with the 1 face of the flange 11, the air vent 14 may be positioned otherwise than as shown, or may be omitted, the retainer 15 may be attached to the container neck 21 other than... by screw threads, other means thanthose shown for preventing th'eunretarded down ward movement of the valve flap 13, and v i and thicker than said flange, the free portion of the valve member abutting upon the flange when in normalposition. i
